* qed.c: replace QEMUOptionParameter with QemuOptsChunyan Liu2014-06-162-56/+61
| | | | | | | | | | | | | | | | One extra change is to define QED_DEFAULT_CLUSTER_SIZE = 65536 instead of 64 * 1024; because: according to existing create_options, "cluster size" has default value = QED_DEFAULT_CLUSTER_SIZE, after switching to create_opts, this has to be stringized and set to .def_value_str. That is, .def_value_str = stringify(QED_DEFAULT_CLUSTER_SIZE), so the QED_DEFAULT_CLUSTER_SIZE could not be a expression.

| | | | | | | | | | | | | | | | | | | | | | | | | | sheepdog driver should decide a write request is COW or not based on inode object which is active when the write request is issued. Example of wrong inode update path in the previous driver: 1. drier issues an ordinal write request to an existing object 2. user creates a snapshot of the VDI before the write request is completed 3. the respones for the request is RDONLY, because the VDI is already a snapshot 4. the driver reload an inode object of the new active VDI, then issues a write request again 5. the second write request can be completed 6. driver decide the request is COW or not with the below conditional branch: if (s->inode.data_vdi_id[idx] != s->inode.vdi_id) { 7. the ID of the written object and VID of the new active VDI is different, so the driver updates data_vdi_id[idx] and writes inode object 8. the existing object cannot be seen by the new active VDI, it results object leaking Cc: Kevin Wolf <kwolf@redhat.com> Cc: Stefan Hajnoczi <stefanha@redhat.com> Cc: Liu Yuan <namei.unix@gmail.com> Cc: MORITA Kazutaka <morita.kazutaka@lab.ntt.co.jp> Signed-off-by: Hitoshi Mitake <mitake.hitoshi@lab.ntt.co.jp> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

* curl: implement .bdrv_detach/attach_aio_context()Stefan Hajnoczi2014-06-041-77/+115
| | | | | | | | | | | | | | | | | | | | The curl block driver uses fd handlers, timers, and BHs. The fd handlers and timers are managed on behalf of libcurl, which controls them using callback functions that the block driver implements. The simplest way to implement .bdrv_detach/attach_aio_context() is to clean up libcurl in the old event loop and initialize it again in the new event loop. We do not need to keep track of anything since there are no pending requests when the AioContext is changed. Also make sure to use aio_set_fd_handler() instead of qemu_aio_set_fd_handler() and aio_bh_new() instead of qemu_bh_new() so the current AioContext is passed in.
